Windblown & Construction Dust Information
In dry areas like eastern Washington, dust is a significant air pollution problem in the form of fine particulate matter, or PM10. If you live in eastern Washington, you have probably experienced windblown dust storms, or the effects of construction dust blowing onto nearby properties. From spring through fall, high winds in the Columbia Plateau region can combine with dry weather conditions and unprotected fields to result in dust storms. These dust storms can lead to extremely high levels of particulate matter air pollution. Under air pollution laws, most windblown dust storms are considered “natural events” which are regulated differently than other sources of air pollution. This site contains materials on natural events policies, the problem of windblown dust and its health effects, and particulate matter in general. This site also contains information on dust from other sources. Windblown Dust InformationSeptember 1, 2002 April 27, 2004
